HINGEl SPECIFICATION forming part of Letters Patent N0. 759,890, dated May 1'7, 1904.

Appnaaon ned iprn 20,1903.

T) all whom, 7115 may cmi/cern:

is a specification.

My invention relates to hinges, more particularly the kind'disclosed in Letters Patent No. 725,712 of April 21, 1903.

The hinge forming the subject-matter of my aforesaid patent comprises pivotally-conneeted members,`each of which is made up of an outer-hollow part provided with 1ongi-.

tudnal slots, an inner partheld in the outer part, and a part interposed between the outer part and the inner part and having fins eXtending through the slots in the former, the said lins being designed when the hinge is driven into a hole bored partly in a door-jamb and partly in a door to cut into theV wood and hold the members in place until the door is opened and the members are connected to the jamb and door, respectively.

The object of the present invention is to provide a hinge the members of which have tins cut and turned or otherwise struck up on their Shanks, such iins being advantageous because they may be quickly and easily formed without adding materially to the cost of the hinge and also because they have a knife-edge which adapts them to be easily driven into wood and yet are thick at the base. and consequently adapted to lend strength and rigidity to the members.

l/Vith the foregoing in mind the invention will be fully understood from the following description and claims when taken in connec tion with the accompanying drawings, in which- Figure l is a horizontal section taken through a door and a door-jamb and my improved hinge; Fig. 2, a perspective View of the improved hinge removed; Fig. 3, an enlarged transverse section taken in the plane indicated by the broken line 3 3 of Fig. l, and Fig. 4 an enlarged perspective view of the shank portion of the outer part of one of the hinged members.

Similar letters designate corresponding Serial No. 153,480. (No model parts in all views of the drawings, referring to whichy vA is one member of my improved hinge, B the other member, and O a pintle pivotally connecting the members. rlhe members A B, respectively, comprise an outer part D, formed of sheet metal, and an inner part E, alsoformed of sheet metal. `he parts D are alike in that they have outer end or shank portions of concave-convex, preferably semicircular, form in cross-section and shoulders c at the inner ends of said portions but they differ in that while the part -D of member A has two barrels d with a space between them the part D of member B has but a single barrel e, said barrel e being designed to be arranged between the barrels Z and, together with the same, receive the pintle. The inner parts E of the members A B have angularly-disposed and rounded portions f at their outer ends designed to rest iiush with the outer ends of the parts D, curved lips g at their inner ends designed to enter under and conform to the barrels of parts D, and lateral projections L shaped to enter the recesses of the parts D back of the. shoulders c. l/Vhen the parts E are arranged in the parts D as shown and described, it will be seen that they will rest finsh with the inner edges of the parts D, and in consequence the members A B will respectively present the appearance of being formed in one piece. It will also be observed that when screws F are passed through registered apertures in the parts E and D and into a door and door-jamb to connect the members to the same said screws will also serve to secure the parts E in the parts D. However, the parts E may be secured in the parts D by means other than the screws F--as, for instance, by braz ing-without involving a departure from the scope of my invention.

My present invention consists in providing on the outer sides of the shank portions Z) of parts D longitudinal fins Ur, which are sheared or cut and turned out from the portions at about the angle shown in order to enable them to cut into the Wood diagonally across the grain when the hinge is Vdriven into position,

IOO

to the application of the hinge. Said ns G, formed as stated, are cheap and strong, and they are also advantageous, since they have a thin cutting edge adapted to be easily driven into wood and a thick base calculated to reinforce and lend increased rigidity and strength to the hinge portions that are driven into the wood.

In applying the hinge the door (indicated by H in Fig. l) is fitted and placed in the position in which it is to hang, and a hole is bored partly in the door and partly in the jamb, (indicated by z`,) the feed of the point of the auger-bit being started in the crack between the jamb and door. which I have deemed it unnecessary to illustrate, is then placed between the members A and B, and the hinge is driven into the hole by hammer-blows applied to the barrels, so that the fins G out into the wood and hold the members A B in place, after which the door is opened and the screws F driven home.

Because of the members A B being formed of pieces of sheet metal they are susceptible of being very easily and cheaply manufactured and are also strong and well capable of withstanding the usage to which hinges are ordinarily subjected. I do not desire, however, to be understood as confining myself to forming the members A B of sheet metal, as my improved fins G may be provided on members of any kind of metal without departure from the scope of my invention.

A centering-plate,

all parts included in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of said embodiment. Such changes or modifications may, however, be made in practice as fairly fall within the scope of my claims.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1sd

l. A sheet-metal hinge member having a sh ank, and one or more longitudinal fins on the shank; the said fins being sheared from and turned outwardly on the shank, and having, in consequence, sharp longitudinal edges and thick bases.

2. A hinge member comprising an outer, hollow part, of sheet metal, having a shank portion, and one or more longitudinal ins thereon; the said fins being sheared from and turned outwardly on the shank, and having, in consequence, sharp longitudinal edges and thick bases, and an inner part, of sheet metal, held in the hollow, outer part, Hush with the inner side thereof.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
